Our understanding is growing quickly.
While it is always a great worry to hear of potential side effects of a vaccine, we also need to compare that with the illness itself. Excerpted from the American Academy of Pediatrics:
Across all ages, the risk of myocarditis was almost 16 times higher for people with COVID-19 compared to those who aren’t infected. The myocarditis risk is 37 times higher for infected children under 16 years and seven times higher for infected people ages 16-39 compared to their uninfected peers.
… small risk of myocarditis after receiving an mRNA COVID-19 vaccine. A June study showed … males ages 12-29 years — the group with the highest rates of myocarditis after vaccination — … 39 to 47 cases of myocarditis for every million second doses of vaccine. [Ed. ~0.004%] … benefits of vaccination outweigh the risks.
